Forgot to mention... We love the boating here, having relocated from the Annaplois, MD area. The boating season is quite long - very comfortable temperatures from late March through late November and usually a week each month during the winter that has warn weather. Lake Wylie is never very crowded and has lots of rivers off the main channel to explore or just anchor out. Lot of water sports, fishing, etc. Boats tend to range from 20-25 foot bowriders, lots of pontoons, ski boats, jet skis, and plenty of larger cruisers. There is only one restaurant with slips on the lake, but it is pretty nice.
I think Lake Norman is more active (and it is 2-1/2 times larger) but I hear there is also more partying which isnt what we were looking for.
